Procedure

250 mg (0.692 mmol) of the compound from example 53 and 190 mg (0.692 mmol) of BEMP were initially charged in 12 ml of dimethylformamide, and a solution of 98 mg (0.692 mmol) of iodomethane in 3 ml of dimethylformamide was added dropwise at 0° C. within 10 min. The mixture was stirred at 0° C. for 20 min. Subsequently, the reaction solution was concentrated under reduced pressure and the residue was purified by means of preparative HPLC (eluent: methanol/aqueous 0.1% ammonia solution=65:35). The residue was stirred with acetonitrile and filtered with suction, and the solids were dried under high vacuum. 50 mg (19% of theory) of the title compound and 78 mg (30% of theory) of example 54 were obtained.
